Title: PNEUMATIC TIRE, PNEUMATIC-TIRE MOLD, TWO-DIMENSIONAL-CODE ENGRAVED-MARK TESTING METHOD, AND PNEUMATIC-TIRE MANUFACTURING METHOD
Abstract:
According to the present invention, provided on the surface of a tire side of a pneumatic tire is: a two-dimensional code that forms a dot pattern by using two types of light and dark elements formed so as to be distinguishable from each other due to unevenness of the surfaces thereof; or a planned region in which the two-dimensional code will be located. Furthermore, provided on the surface of the tire side are at least two protruding or recessed marks that are provided at the same position in a first direction from among a tire radial direction and a tire circumferential direction and that are separately provided at different positions in a second direction from among the tire radial direction and the tire circumferential direction, so as to sandwich an outer edge of the two-dimensional code or the planned region in which the two-dimensional code will be located, from both sides in at least one of the tire radial direction and the tire circumferential direction.
